Abstract
The utility model relates to a mounting structure of active rotation-speed sensor for vehicle driving wheels, which comprises an active rotation-speed mounted on a hub bearing outer race of the driving wheel and whose sensor whose induction tooth ring is assembled on a hub bearing inner race of the driving wheel. Based on axial sensing mode, when the bearing is driven by the driving shaft of vehicle, the induction coil rotates to change the magnetic density of the Hall elements passed therethrough, resulting in the change in Hall voltage, the Hall elements output a quasi-sine-wave voltage that is further transferred to and processed by the electronic control unit of antilock brake system. The utility model has advantages of compact structure, reasonable design, no influence of output signal voltage amplitude on rotation speed, high frequency response, and good resistance against electromagnetic interference. The utility model can meet the requirements of wheel speed inspection in the update automotive active safety technology. Additionally, induction tooth ring is made of magnetic material and assembled on the bearing, thereby saving space and reducing weight.
Description
Technical field
The utility model relates to a kind of active wheel speed sensor mounting structure on the automobile driving wheel hub bearing.
Background technology
At the automobile active safety technical elements, anti-lock braking system in automobiles, Driving Antiskid Control System and Electronic Stability Program (ESP) all need to adopt wheel speed sensors, existing wheel speed sensors is passive electromagnetic sensor mostly, the output signal voltage amplitude is subjected to the influence of rotating speed, frequency response is low, a little less than the anti-electromagnetic interference capability.In addition, the required assembly space of existing wheel speed sensors is bigger, and self is heavier, can not satisfy the requirement that the automobile active safety technology detects wheel speed.
Summary of the invention
This practical purpose is to provide a kind of automobile driving wheel active wheel speed sensor mounting structure at the deficiency of prior art existence, adopts active active sensing mode, improves and guarantee the precision of wheel speed signal, saves assembly space simultaneously, weight reduction.
The utility model is realized by such technical scheme: adopt active active wheel speed sensor, utilize the hall sensing principle to guarantee and improve the precision of wheel speed signal.The utility model is integrated in induction gear ring on the driving wheel hub bearing inner ring, wheel speed sensors is installed on the driving wheel hub bearing outer ring, adopt axial sensing mode, when truck drive shaft drives the bearing rotation, induction gear ring is also along with rotation, make and to pass that the density of line of magnetic force of Hall element changes in the sensor, thereby cause the variation of Hall voltage, Hall element will be exported a quasi-sine-wave voltage, and the electronic control unit that is transferred to anti-lock braking system by lead is handled again.
It is reasonable to the utlity model has compact conformation, and the output signal voltage amplitude is not subjected to the influence of rotating speed, the frequency response height, and the advantage that anti-electromagnetic interference capability is strong can satisfy the requirement that up-to-date automobile active safety technology detects wheel speed.Induction gear ring adopts magnetic material also to be integrated on the bearing, has not only saved space but also weight reduction.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1: wheel speed sensors 1 of the present utility model totally is mounted on the driving wheel hub bearing 2, is positioned at steering knuckle 3 inboards.The induction gear ring of wheel speed sensors is integrated on driving wheel hub bearing 2 inner rings, and wheel speed sensors 1 is installed on driving wheel hub bearing 2 outer rings, and three bolts of steering knuckle 3 usefulness and driving wheel hub bearing 2 link together.Induction gear ring is the magnetic rubber gear ring.When truck drive shaft drives the bearing rotation, be integrated on driving wheel hub bearing 2 inner rings induction gear ring also along with rotation, make and to pass that the density of line of magnetic force of Hall element changes in the sensor, thereby cause the variation of Hall voltage, Hall element will be exported a quasi-sine-wave voltage, and the electronic control unit that is transferred to anti-lock braking system by lead is handled again.
